The diphenyliodonium salt （DPIOC）/triethylamine （TEA） is used as photoinitiator for radical photopolymerization. It was found that a ground state CT complex formed between DPIOC as electron acceptor and TEA as electron donor

which results in extending the photosensitivity range of DPIOC/TEA system up to above 500nm compared with DPIOC alone. The kinetic studies on photopolymerization of methyl methacrylate （MMA） were carried out in CH

O （14: 1

v/v） mixture solution at 30℃by dilatometer. The results obtained show that the polymerization rate （R

） increases with increasing concentrations of DPIOC and TEA with exponent 0. 65 and 0. 62 respectively. The activation energy E

and 0.045 respectively. The other influence factors and reaction mechanism were also discussed.
